如何区别Waterproof Water Repellent Water Resistant

区别:

一)疏水——Water Repellent

“疏水”是指在AATCC(American Association of Textile Chemists and Colorists,美国纺织化学师与印染师协会)技术规范(AATCC Technical Manual)里定义的Water Repellent。

按照AATCC的定义,“疏水性”是指面料防止被水浸湿的能力,而“抗水性”是指面料防止被水浸湿及防止水透过的能力。对于疏水性通常使用两种测试方法,AATCC TM 22(TM:Test Method,测试方法,下同)里定义的“喷雾测试(Spray Test)”和TM 70里定义的“滚筒动态吸收测试(Tumble Jar Dynamic Absorption Test)”。通过测试,可以评估出面料相对的疏水性,通常用一个0~100的值来表示。一般来说,疏水性到80~90的面料,就可以挂上“Water Repellent ”的标签了。

关键的一点是,疏水性度量的是面料吸收的水的多少,而不是面料透过的水的多少。

二)、抗水——Water Resistant

“抗水性”是指面料防止被水浸湿及防止水透过的能力。AATCC定义了3种测量拒水性的方法:TM 35 “雨测试(Rain Test)”,TM 42 “冲击渗透测试(Impact Penetration Test)”和TM 127 “流体静压力测试(Hydrostatic Pressure Test)”。

冲击渗透测试用一定分量的水在一定高度落下冲击面料表面,最终是以透过织物的水的重量来衡量。至于流体静压力测试,则反倒是最熟悉的测试方式,也就是在面料一侧加压,以在面料另一侧出现水珠时的压力作为面料的抗水性指标,也就是通常说的,防水能力为…毫米水压。这个测试的重要意义在于明确区分了面料的“抗水性”和面料/纤维的疏水性。面料的抗水性和纤维或纱线的疏水性、粗细、形状、织法、面料的空间结构、微孔大小等多方面因素共同相关。

三)、waterproof(防水)

一般是指在布料底面做胶底,分coating和lamination两种,coating就是常说的涂层,lamination是复合一层防水料在后面。这个才是真正的防水,一般防水布料表面也有分做 W/R和不做W/R的,W/R+W/P当然就比单纯的W/R或W/P好。

防泼水没有水压指标,一压就全面渗水。欧洲的能够称为waterproof的是1000mm。一般最低防水度600mm勉强叫防水。

应该说,防水的衣服必须有seam taping(在衣服里面缝骨处烫一条防水压胶)。

渗透/着色探伤有什么区别

是一回事,着色(渗透)探伤的基本原理是利用毛细现象使渗透液渗入缺陷,经清洗使表面渗透液去除,而缺陷中的渗透残留,再利用显像剂的毛细管作用吸附出缺陷中残留渗透液而达到检验缺陷的目的。 二种说法都是利用渗透液来显示构件表面缺陷的一种探伤方法。 其操作过程是:首先将具有较强渗透性的渗透液涂在构件表面,使之渗于微小缺陷中,然后清除表面多余渗透液,之后再涂一层显像剂,使残留在缺陷中的渗透液被吸附,在表面显示出缺陷来。 按渗透液的不同,可分为荧光渗透探伤和着色渗透探伤。 查看原帖

如何安装metasploit

Metasploit是一款开源的安全漏洞检测工具,可以帮助安全和IT专业人士识别安全性问题,验证漏洞的缓解措施,并管理专家驱动的安全性进行评估,提供真正的安全风险情报。

首先在Metesploit官网下载最新的安装包。下载地址:

下载之后记得比对校检码,如果校检码不符合,说明安装包在下载过程中损坏,需要重新下载。损坏的安装包在安装的时候会出现has no VFS data的错误。笔者就因为没有比对校检码,导致一直出错。校检码比对方法:打开终端,切换到下载目录,输入命令:sha1sum 安装包 结果类似于

47a56013000dded69956da0a827c910a9ced48c7 metasploit-latest-linux-installer.run

将前面的这串字符串与metasploit官方给出的SHA值比较,如果吻合,说明安装包是完整的。SHA值地址:verify-download/

然后开始在Ubuntu下安装。

先安装ruby。命令:sudo apt-get install ruby

给予安装包执行(x)权限。sudo chmod u+x 安装包

运行安装包。sudo ./安装包

这时候就会出现安装界面,一直下一步就好了。

在这里向大家推荐一本关于Metasploit的书:Metasploit:The Penetration Tester's Guide.中文名译为Metasploit渗透测试指南。笔者有英文版的PDF。

可以吧

学习网络安全工程和网络营销哪个好

其实有一个专门的课程,是为网络安全工程师量身定做的。。CEH课程。也叫道德黑客。。我帮你找一下课程目录啊、、、、1.EthicandLegality(黑客道德与法律法规)2.Footprinting(踩点)3.Scanning(扫描)4.Enumeration(列举)5.SystemHacking(系统入侵)6.TrojansandBackdoors(木马和后门)7.Sniffers(数据包监听)8.DenialofService(拒绝服务)9.SocialEngineering(社会工程攻击)10.SessionHijacking(会话劫持)11.HackingWebServers(网站入侵)12.WebApplicationVulnerabilities(网站应用程序漏洞)13.WebBasedPasswordCrackingTechniques(网站密码破解技术)14.SQLInjection(数据库注入)15.HackingWirelessNetworks(无线网络入侵)16.VirusandWorms(病毒与蠕虫)17.PhysicalSecurity(物理安全)18.HackingLinux(Linux系统入侵)19.EvadingFirewalls,IDSandHoneypots(防火墙、入侵检测系统和蜜罐系统规避技术)20.BufferOverflows(缓冲区溢出)21.Cryptography(密码学)22.PenetrationTesting(渗透测试)课程全是英文的。我看过。。讲的很细。尤其是那些实验工具。。。不过一点不好就是都是美国人平常用的,在国内用的工具跟课程上有点差距。。但是基本都差不多。以踩点为例子。踩点课程可能涉及到facebookyoutube等。。。我们可能用不到,但我们可以用人人网。。各大论坛。。后面的课程工具比较同意,比如无线破解可能使用BT5缓冲溢出可能使用metasploit工具集、、网络安全工程师这个岗位,除了渗透测试,还有安全服务,安全产品集成。建议先从网络开始学起。因为这些都离不开网络。。学习网络的书有TCP/IP路由技术。。
